It's been worth my time in FREE product(s) alone!!! The points reward system has always just been an extra for me and I haven't paid much attention to them until recently when they partnered with Mypoints.com and I now have over 20,000 mypoints points to redeem

In the new system I am a level 6 - Sweet Bee.
How long and how often you get offered campaigns varies and it has been feast or famine for me. Several campaigns then nothing for a few months then several again. I try to do at least the minimum of 2-3 reports per item but sometimes I've done less, sometimes more. Be open to trying new things and answer questionaires as such. You usually receive a full size product for you to try or a coupon to get the item free at your local stores and then various buzz tools - samples, coupons, pamphlets to pass out.
We have gotten and tried....(just a few, not all)
books - full edition by various authors depending on campaign
chapstick naturals - samples and coupons
hillshire farms salad kits - free Q's
Off Lamp and bug spray - 2 full size spray, 1 lantern, coupons
Sunscreen - 2 full size cans and coupons
Grey Poupon - 3 full size jars and coupons
Claritin Reditabs - 1 package and coupons
Ziplock Big Bags - 3 boxes of big bags and coupons
Sonicare toothbrush - received 2 - 1 with UV sanitizer/1 regular
Take 5 candy bars - box of samples (about 30) - this was my 1st campaign!
Aveeno Positively Ageless Cream - 1 full size & coupons
Oust Disenfectant - 2 full size cans and Q's for free product
Barilla Tortillini - 2 free packages, potholder, Q's for free product
Eucerin Daily Replenishing - 2 full size, samples, and coupons
So I think that when you look at the value of the FREE products you will find that it is worth your time. Each report takes maybe 5 minutes to fill out and I buzz during normal conversations - co-workers, friends, family. They all know that I am the freebie queen and go to person on new products so they usually will ask ME if I have anything new now.
